Association versus Causation Confounding Variables Observational Studies vs Experiments Randomized Experiments (5 cards)
1
Q
Association
A
Two variables are associated if values of one variable tend to be related to values of the other variable
2
Q
Causation
A
Two variables are casually associated if changing the value of the explanatory variable influences the value of the response variable
3

A third variable that is associated with both the explanatory variable and the response variable
4
Q
